Abstract:
Atrial arrhythmias are common in patients with diabetes mellitus (DM), and despite recent advances in pharmaceutical and invasive treatments, atrial fibrillation (AF) and atrial flutter (AFl) are still associated with substantial mortality and morbidity. Clinical trial data imply a protective effect of sodium-glucose cotransporter-2 inhibitors (SGLT2is) on the occurrence of AF and AFl. This review summarizes the state of knowledge regarding DM-mediated mechanisms responsible for AF genesis and recurrence but also discusses the recent data from experimental studies, published trials and metanalyses.
Insights
Diabetes mellitus (DM) increases the risk of atrial arrhythmias like atrial fibrillation (AF). Sodium-glucose cotransporter-2 inhibitors (SGLT2is) show a protective effect against AF and atrial flutter (AFl) in patients with DM.
Area of Science:
- Cardiology
- Endocrinology
- Pharmacology
Background:
- Atrial arrhythmias, including atrial fibrillation (AF) and atrial flutter (AFl), are prevalent in patients with diabetes mellitus (DM).
- Despite advancements in treatment, these conditions remain significant causes of mortality and morbidity.
- Existing treatments for DM-related atrial arrhythmias have limitations.
Purpose of the Study:
- To review the mechanisms linking diabetes mellitus to atrial arrhythmia genesis and recurrence.
- To evaluate the protective effects of sodium-glucose cotransporter-2 inhibitors (SGLT2is) on AF and AFl occurrence.
- To synthesize current knowledge from experimental studies, clinical trials, and meta-analyses.
Main Methods:
- Literature review of experimental studies on DM-mediated mechanisms.
- Analysis of published clinical trials investigating SGLT2is.
- Synthesis of data from meta-analyses concerning SGLT2is and atrial arrhythmias.
Main Results:
- Diabetes mellitus contributes to the development and persistence of atrial arrhythmias through specific pathophysiological pathways.
- Clinical trial data suggest a protective role for SGLT2 inhibitors in preventing AF and AFl.
- Meta-analyses corroborate the beneficial effects of SGLT2is in this patient population.
Conclusions:
- Understanding DM-mediated mechanisms is crucial for managing atrial arrhythmias.
- SGLT2 inhibitors represent a promising therapeutic strategy for reducing the incidence of AF and AFl in diabetic patients.
- Further research should explore the full potential of SGLT2is in cardiovascular protection in DM.
